✅ [Developed by Sho Oosuga, a Judo Therapist with 35 years of experience, and supervised by a university hospital physician.] This thumb and wrist support is developed based on 35 years of clinical data by a specialist with thorough knowledge of Japanese wrist and thumb sizes and the structure of the CMC joint. It has been refined over 3 years with a focus on "quality," "durability," and "support."
[Important Notes for First-Time Use] If you feel tightness or numbness in your thumb when you first start using it:① The fabric can be loosened by gently pulling it.② Please wash it by hand before use.③ The fabric is intentionally stiff when new to ensure durability. When you first start using it, wear it for short periods and gradually increase the duration as you get used to it.
[Please Confirm] If you feel the thumb is too tight, align the seam in the center and gently pull the fabric to loosen it. This will allow you to experience a better fit as you use it.
[Note: The instruction manual describes how to wear the right-side support. For the left side, please refer to the instructions for the right side.]
✅ This is a comfortable thumb and wrist support that firmly secures from the thumb to the wrist. It is ideal for symptoms related to the CMC joint, the base of the thumb, and De Quervain's tenosynovitis. The thumb and wrist can be adjusted to your desired tightness. This thumb and wrist support provides firm joint support while being resistant to slipping. The wrist strap uses a cross-support method for a secure fit. The thumb joint, which is prone to strain, can be adjusted and fixed with the strap. By firmly securing the base of the thumb and the wrist, movement is restricted. It provides excellent support for work, hobbies, and household chores. The thin material allows it to be worn under rubber gloves.
